钠离子是人体体液中最重要的阳离子之一,对维持细胞内外的渗透压起主要作用。随着离子电极医用化的研究钠电极在临床上的应用日臻广泛。自七十年代末,国际上相继有IL、康宁、奥立龙、曼·海姆、常光、ENI、AVL、雷度和贝克曼公司纷纷推出不同型号的医用钾钠离子分析仪,这些仪器中钠离子的检测均是采用玻璃敏感膜钠离子选择电极。 Sodium ion is one of the most important cations in human body fluids and plays a major role in maintaining the osmotic pressure both inside and outside cells. With the medical research of ion electrodes, the clinical application of sodium electrodes is becoming more and more widespread. Since the late seventies, IL, Corning, Oleg Lung, Mannheim, Chang Guang, ENI, AVL, Lei Duo and Beckman companies have introduced different types of medical sodium potassium analyzer, these instruments Sodium ions are detected using glass-sensitive membrane sodium ion selective electrode.
